[ADAP-786] Hints for dbt init auto-profile completion don't display in as helpful a way as they could

[gwenwindflower]

The hints referenced here:

dbt-snowflake/dbt/include/snowflake/profile_template.yml

Lines 4 to 5 in fd28b35

	account:
	hint: 'https://<this_value>.snowflakecomputing.com'

Look a little confusing in practice.

I think making them more descriptive like 'What is your account? [The value here .snowflake-computing.com]' etc will help the init flow.
